英语六级作文Food-Safety(食品安全)精品文档Food SafetyCurrently, many problems concerning the safety of food have popped up. As for me, I believe at least three factors account for this issue.First, I observe that profits drive many food producers to commit illegal things. They aim to gain more money at the expense of consumers health. Second, the overuse of agricultural pesticide has resulted in the degradation of food quality. The excessive pesticide bears enormous health hazard for people. Furthermore, some food producers inject hormones into domestic animals so as to make them grow more quickly and thus they can turn in more profit. As a result, peoples health has been seriously disturbed.All in all, food safety is such a great concern, and we all should establish laws and implement them effectively to avoid producing toxic foods.来源：Competition is a common phenomenon in our social life. We compete when we play games and when we try to do better than others in our study. There is constant competition for academic degrees, jobs, customers, money and so forth. In a sense, competition is one of the motive force to the development of society.In fact, the only way our world reward people is to give laurels to the winners, not to the losers. What is more, by attempting to compete at different activities, we learn to win and lose, gain experience and know our strengths and weaknesses. Competition prepares us for the tough things in life.To go ahead, to acquire possession, we should be competitive. To us, industriousness and ambition are positive values.Whether in games, in study or in business alike, the aim is to win the game, the degree, the trophy, and the contract. Learning to be competitive is clearly the best preparation for life.来源：2011年12月英语六级考试作文预测之低碳 大学英语六级作文预测主题：低碳 1. 低碳生活受到人们的普遍欢迎 2. 低碳生活方式非常有好处 3. 我们应该如何去做 范文 Nowadays， there are a considerable number of individuals who prefer to lead a low-carbon lifestyle which find expression in the fact that more and more commuters are using public transportation system in their daily life.
